Fuzzing is a process that is used during a penetration testing to find out if the application is vulnerable, the process come by sending incorrect data to the targeted application in order to cause a failure or an error situation that security analyst will use as a PoC in their report.

Fuzzware allows to make testcases as required:

fuzz a file format such as XML file.

fuzz network protocol or a network service by sending a predefined network packets.

I tried fuzzing an xml file with Fuzzware. Eventhough the xml file is valid and I use it everywhere, when I try fuzzing, it gives me a null pointer exception. In the command line, I get the following error :
“System.ArgumentNull exception : value cannot be null. Parameter name : key”
